It has been so long since I did this that I don't remember how I did it. I have a pdf file in my documents and want to upload it so that it displays without having to show the link to click on. So in otherwords, when someone clicks on the page on the website i want the info in the file to automatically be on the page.
If you want the information on a page, then you must cut and paste and put it on a page. You may earlier have seen a pdf open in your browser instead of the proper program. But that is caused by browser settings, not anything you do on the page.
But the way to make pdf info available, is either to upload the file and link to it, or move the information to a webpage by cutting and pasting.
